Roofing Services in Portland, OR
J&K Roofing has been serving Portland since 1956, long enough to know how different a Sellwood bungalow, an NW alphabet-district Craftsman, and a new infill on the eastside really are when it comes to roofing.
From the historic neighborhoods of inner SE and NW to the newer outer-east subdivisions, we work across all of Multnomah County. Our crews handle single-shingle repairs, full tear-offs, new construction, and everything in between.

Why Roofing Is Different in Portland
Portland’s roofing challenges aren’t one-size-fits-all. The city has wildly different microclimates and housing stock depending on where you are.
Inner SE / NE / SW: Mature tree canopy (especially Sellwood, Eastmoreland, Laurelhurst, Alameda) means heavy moss pressure and constant shade-moisture cycling. Many of these homes are 80–110 years old, with original sheathing that may be tongue-and-groove rather than plywood, which adds time and cost on tear-offs.
NW alphabet district / West Hills: Steeper roofs, often slate or cedar shake originally. Higher-spec replacements common.
Outer East / Gresham-adjacent: Newer subdivisions, less tree canopy, more straightforward composition replacements. The challenge here is age: a lot of housing stock is hitting the 25–30 year mark all at once.
Across all of Portland: 36 inches of rain per year, frequent freeze-thaw in shoulder seasons, and historic-district considerations on certain streets that can affect material choices. We pull the City of Portland permit on every project.

Questions
Frequently Asked Questions in Portland
Do I need a permit to replace my roof in Portland?
Yes. The City of Portland’s Bureau of Development Services requires a building permit for any re-roof, including layovers and full tear-offs. We handle the permit application and inspection as part of the job. Permit fees scale with project value, usually 1.5–3% of the contract.
Does my historic-district designation affect my roofing options?
Sometimes. Streets with formal historic-district designation (Ladd’s Addition, Irvington, parts of Alphabet District, etc.) may have material-type restrictions, such as requiring cedar shake or specific shingle profiles to maintain the streetscape. We’ve worked through these reviews before; tell us your address up front and we’ll flag any restrictions during the estimate.
What's the best roofing material for Portland's climate?
For most Portland homes, Class 4 impact-rated architectural asphalt shingles are the right call: 30–50 year manufacturer warranties, holds up well to PNW moisture cycles. Standing-seam metal is a strong second option for steep roofs and tree-heavy lots since moss and debris slide off rather than build up. Cedar shake is still possible (and sometimes required by historic district) but requires more maintenance and a shorter usable life.
What's a typical roof-replacement cost in Portland?
For a standard 1,800–2,200 sq ft single-family home with architectural shingles: roughly $13,000–$24,000. Older homes with tongue-and-groove sheathing, multiple layers to tear off, or steep/complex roof lines can run higher. Standing-seam metal generally adds 60–100% over asphalt for the same footprint.
When is the best time to replace a roof in Portland?
Late June through early October is the reliably dry stretch and our peak season. Book 4–8 weeks ahead. Tear-offs in late fall through spring are doable when we get a confirmed dry window, but we don’t expose decking on a forecast we don’t trust.
Do you handle moss treatment and gutter cleaning?
Yes. Inner-Portland homes with mature canopy typically need moss treatment every 2–3 years to keep growth from lifting shingles. We do zinc-strip applications, hand-removal where needed, and full gutter and valley cleanouts.
What's your warranty?
Manufacturer warranty on materials (typically 30–50 years on architectural shingles, prorated). J&K’s labor warranty is 10 years on full replacements, transferable with the home.
